Copying large files consumes too much memory

Have a look at the bios and see if the SATA controller is set to ACHI if so try IDE mode for both SATA chanels for the two drives ACHI mode has issues on a lot of boards.

Also are you running with no swap file?

Swap file is set to 2GB (2048MB) on disc D manually.
SATA controller is set to IDE in BIOS (other options are raid and achi, but never used them).

So your swap file is on the second drive I have done that on XP and Vista without issue but I have not tried in 7... I would put the swap file back on C and system managed as mentioned and see if that helps.

The swap usually performs better on the beginning track of a second physical drive I have always had my system setup that way but I did not do it when I installed Windows 7 so for the sake of trying to figure this out I would just go with what we know should not be a problem.

Swap file was set to D drive yesterday, until then it was windows managed as default. I change it to D drive only to find out is there a problem with copying files which I first time discovered some 5 days ago. I will set it to default setting again.

@Dzomlija: I will try Microsoft SyncToy 2.1 later and give feedback here

Try swapping the SATA cables and see if it causes the reverse of the issue you are having or even try to replace them if you have spares

run the diagnostic tools for those drive makes and see what they report also

I'd think Nod32 Antivirus is scanning those xfering file[s] thus slowing everything down.

Try disabling Nod32 [r-click icon near clock - turn off 'antivirus/antispyware']

transfer big file[s] and once completed remember to restart Nod32 protection

Already tried disabling file protection in NOD32, that's not the problem. Or maybe should I try to uninstall NOD32?

Try turning off Advanced Heuristics in NOD32, I also had this problem, but on my old PC with XP, and turning this off solved the problem completely.
